Johanson Manufacturing produces High Quality Trimmer Capacitors, Non Magnetic Variable Inductors and Microwave Tuning Elements.
Login  

Non-magnetic Capacitors are designed specifically for low magnetic signature applications such as Magnetic Resonance Imaging, Neuclear Magnetic Resonance, and other medical applications. These high stability Non-magnetic Capacitors feature the one piece self locking constant torque mechanism along with special non-magnetic construction for superior performance in very high strength magnetic fields. Non0magnetic Capacitors are available in multi-turn and single turn styles and various configurations.
